1/8. Successful root coverage: a human histologic evaluation of a case.

    connective tissue grafts combined with pedicle grafts (subepithelial grafts) have been shown to be effective in obtaining root coverage. Unfortunately, little is known about the histology of the results in humans. This is a case report of a tooth with a recession defect that was treated with a subepithelial graft. Complete root coverage was obtained. However, at 5 months postoperative the tooth had to be extracted because of a vertical root fracture. With the patient's permission, a small collar of tissue was removed with the tooth. The sample was processed and evaluated histologically. The results revealed areas of regeneration, with new bone, cementum, and connective tissue attachment coronal to the original gingival margin. No bone grafts or guided tissue regeneration membranes were used. This case report confirms that regeneration is possible with subepithelial grafts.

2/8. Decoronation of an ankylosed tooth for preservation of alveolar bone prior to implant placement.

    A 12-year-old patient sustained avulsions of both permanent maxillary central incisors. Subsequently, both teeth developed replacement resorption. The left incisor was extracted alio loco. The right incisor was treated by decoronation (removal of crown and pulp, but preservation of the root substance). Comparison of both sites demonstrated complete preservation of the height and width of the alveolar bone at the decoronation site, whereas the tooth extraction site showed considerable bone loss. In addition, some vertical bone apposition was found on top of the decoronated root. Decoronation is a simple and safe surgical procedure for preservation of alveolar bone prior to implant placement. It must be considered as a treatment option for teeth affected by replacement resorption if tooth transplantation is not feasible.

3/8. Treatment of avulsed teeth with Emdogain--a case report.

    The present case report describes the reimplantation of avulsed teeth with the treatment of Emdogain. Case was avulsed right maxillary permanent central and lateral incisor in a 9-year-old girl suffering from a traumatic injury. After pretreatment of avulsed teeth, Emdogain was applied to the root surface and into the extraction socket with subsequent replantation of the tooth. Evaluation parameters included horizontal and vertical percussion sound and periapical radiographs. At 1-2-6-12-month follow-up period, the clinical and radiographic appearance of the teeth showed resolution of mobility and no signs of replacement resorbption.

4/8. Cemental tear related to rapid periodontal breakdown: a case report.

    Cemental tears have been described both in exposed and unexposed cementum. The phenomenon is believed to be elicited by overloading or acute trauma from occlusion. In this case report a patient, with a history of periodontal health, presented with an acute periodontal lesion on the distal aspect of a bridge abutment tooth. Periapical radiographs demonstrated an extensive vertical intrabony defect adjacent to the vital abutment tooth containing a radiopaque "foreign body." Histological examination of the surgically removed "foreign body" revealed a piece of dental cementum with some attached soft tissue. The lesion responded well to a surgical approach. Healing was uneventful and periodontal health was restored. This case illustrates that cemental tear should be considered as a differential diagnostic entity in isolated sites with rapid periodontal breakdown.

5/8. Severe external root resorption arrested by conventional endodontic treatment.

    A case is presented of inflammatory external root resorption detected on radiographic examination. Conventional endodontic treatment, including calcium hydroxide dressing for two weeks and obturation of the root canal system using the vertical compaction of warm gutta-percha technique was a simple and effective treatment modality for arresting the resorptive process and maintaining the integrity of the patient dentition.

6/8. Vertical control by combining a monoblock appliance in adult class III overclosure treatment.

    Monoblock appliances were used in combination with intermaxillary elastics for treatment of adult skeletal Class III patients. The patients showed predisposing upper incisors problems, significant mobility in patient 1 and root resorption in patient 2, which contraindicated direct intrusion of the incisors. Using the monoblock with selective extrusion of the molars, a clockwise rotation was induced to reduce overbite and to achieve a better profile. It was also possible to reduce the excessive force to the upper incisors during and after treatment, which improved incisor mobility to a physiologic extent (patient 1) and prevented further progression of root resorption (patient 2). Stability was high after the 2-year follow-up, which suggests a stable vertical control approach by using the monoblock appliance in combination with a fixed appliance in adults.

7/8. root resorption associated with placement of a ceramic implant. Report of a case.

    Ceramic grafting material was used to treat a vertical osseous defect associated with a maxillary left lateral incisor tooth. The area was monitored at maintenance appointments. root resorption was detected radiographically 12 months after grafting. At 18 months, resorption was evident clinically in the presence of moderate inflammation.

8/8. root resorption associated with hydroxyapatite particles: a case report.

    A case report of an unusual root resorption reaction associated with a graft of hydroxyapatite particles is presented. The hydroxyapatite particles were grafted to treat vertical infrabony defects at the distal aspect of the maxillary left canine and on the mesial side of the mandibular right first molar. The graft sites were monitored at maintenance visits. root resorption was observed radiographically 9 to 10 months after grafting. The lesions were restored with a light-cured glass-ionomer cement and/or a resin composite. Possible etiologic factors associated with this condition are discussed.
